WiseSeal® End-Grain Sealant is a water-based sealer specifically designed to protect the freshly cut ends of boards. Because end cuts of decking and lumber dry out faster than the center, they are more prone to developing unsightly end checks (drying splits) that can quickly spread. These cuts also expose the material to the elements, making them vulnerable to water intrusion, which can lead to swelling, mold, mildew, warping, and cupping.

WiseSeal® has been proven to enhance the structural integrity of hardwoods, thermally modified wood, softwoods, pressure-treated (PT) lumber, and composite materials.

Paintable & Stainable!

Ideal for protecting decking, siding/cladding, railings, steps, log ends, turning blanks, and other exposed end grains, WiseSeal® provides long-lasting protection for both inventory and on-site materials. This eco-friendly, durable, water-based formula forms a flexible, breathable barrier at the cellular level, giving wood exceptional protection. After 24 hours, the product can be painted or stained for a finished look.

Due to differences in wood species, variety of climatic conditions, and an individual's usage methods; results are NOT guaranteed.

One 16 oz container covers 37.5 sq. ft. or 975 end cuts. It's highly recommended to protect end grain cuts to avoid checks and splits. However, due to variations in wood species, climatic conditions, and individual application methods, results are not guaranteed.

To apply WiseSeal®, begin by using a synthetic brush or stain pad, starting from the bottom edge of the board and brushing upward. Wipe off any excess product from the surface, as it may repel future surface coatings. Do not use the product if the air or surface temperature is below 45°F (7.22°C) or above 95°F (35°C), and avoid applying it during rain or if rain is expected. Do not thin the product—mix it well by stirring or shaking thoroughly before use. Test a small area to ensure acceptable appearance and penetration. Apply the first coat to the end cuts, and a second coat can be applied once the first coat is still damp but within one hour. For optimal results, apply in the shade, avoiding direct sunlight. Do not combine WiseSeal® with other waterproofing products, and be sure to remove any excess product, wiping away drips or runs that haven't soaked in.

WiseSeal® is a water-based, ultra-low VOC, eco-friendly sealant that prevents end checks and drying splits while stabilizing wood to resist warping. It penetrates below the surface, creating a flexible, breathable barrier that resists water and mildew penetration. To ensure proper application, clean the board ends before applying WiseSeal®, and after 24 hours, the ends can be painted or stained to match any surface finish or coating color. This non-toxic formula is safe for people, pets, and plants, offering easy soap-and-water clean-up. However, avoid using oxidizers, corrosives, or strippers on treated ends to maintain its protective properties.
